I have some "mystery" passiflora plants in the g-house (seeds came from a store-bought maypop-looking fruit).

I've been noticing some of the leaves on some of the plants are crinkling together, not drying-out crinkling, but rather in good health and as if they are being knitted together but yet not curled under..

In this pic the leave in my hand shows some of it. Note the center of the leaf (not just the edge), see how it is being pulled in?.

Is this something that mites would do?
